What We See in Wheaton Homes
Wheaton has older homes near downtown, some with boilers, plus postwar and 1960s-1990s subdivisions with forced-air systems. A few things come up often:
- Boilers and radiators. Many homes here still heat with steam or hot-water boilers. We service and replace boilers and size them to the radiators, not to the old unit.
- Original ductwork and small returns. Many postwar homes still have the original duct layout with one or two returns. A new system can’t perform if it can’t breathe, so we check airflow first.
- Builder-grade equipment at the end of its life. Many homes here still have the original furnace and AC from when the house was built. At 20+ years, replacement usually beats repeated repairs.

Replacement Costs in Wheaton
Every house is different, but here are honest ranges: AC about $4,000–$8,000; heat pump about $6,000–$10,000 before rebates; furnace about $4,000–$10,000 depending on size, efficiency, brand and location. We install Trane, Carrier, Bosch, Midea, LG, Gree and Goodman, and all equipment comes with a 10-year factory parts warranty, with extended labor coverage included or available depending on the package. In our climate, paying extra for anything above about 17 SEER2 rarely pays back.
Rebates and Utilities in Wheaton
Wheaton homes get electricity from ComEd and natural gas from Nicor Gas. ComEd offers instant discounts on qualifying heat pumps, which is why heat pumps have become a realistic option here. See our heat pump page for current ComEd discount details. The federal 25C tax credit for heat pumps and furnaces ended for equipment installed after December 31, 2025, so if someone is still quoting it to you, ask questions.
Maintenance
Our one-time tune-up is $150 and includes a real cleaning of your equipment. An inspection is $79. Maintenance plans start at $15/month and cover an AC visit before cooling season and a furnace visit before heating season.
Wheaton HVAC FAQ
How fast can you get to Wheaton?
Our Wheeling location is about 20 miles away. Most service calls are same or next day, and emergencies are answered 24/7.
Are there heat pump rebates in Wheaton?
Yes. ComEd offers instant discounts on qualifying heat pumps, and after the discount a heat pump often costs about the same as a straight AC replacement.
Should I replace my furnace and AC at the same time?
Not always. If your AC is old and your furnace is in good shape, a heat pump can replace the AC and take over most of your heating. We’ll look at both and tell you what makes sense.
